Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707816, here are decompositions:

23 + 8707793 = 8707816
53 + 8707763 = 8707816
167 + 8707649 = 8707816
809 + 8707007 = 8707816
863 + 8706953 = 8707816
947 + 8706869 = 8707816
983 + 8706833 = 8707816
1109 + 8706707 = 8707816

Showing the first eight; more decompositions exist.
